The houses in the area we moved into when we came east were built in the early 1970s at a time when building codes were allowing the use of alumin(i)um wire in place of expensive copper wire. By dumb luck we chose to buy a home that had been properly wired, but not everyone was so lucky. Because of their current draw, cookers/stoves/ovens were a particular problem as aging, oxidized connections began to overheat. Then the heating/cooling cycles at the connections accelerated the problem by loosening up the screw connections. I personally know only one couple who have experienced a house fire, but I wouldn't wish it on my worst enemy.
